· Product Overview
Introducing the YITECH Precision Red Anodized Aluminum Spacer — a CNC-machined cylindrical bushing engineered for mechanical spacing, shaft alignment, optical mounting, and aesthetic integration in high-performance hardware systems.
This spacer delivers:
- Vibrant, consistent red anodizing (Type II, 15 μm) — scratch-resistant, UV-stable, and visually striking
- Solid 6061-T6 aluminum construction — lightweight (≈2.7 g/cm³), strong (Tensile: 310 MPa), and non-magnetic
- Tight tolerances: ±0.01 mm on ID/OD, ≤0.01 mm concentricity — ideal for precision assemblies
- Smooth internal bore — no tool marks, perfect for sliding fits or bearing seats
- Zero burrs or micro-cracks — verified via magnified inspection
Unlike generic plastic or zinc die-cast spacers (prone to deformation, fading, or corrosion), our aluminum spacers offer long-term reliability, thermal stability, and premium appearance — whether used in robotics, drones, consumer electronics, or custom machinery.
Perfect for designers who need functional parts that also elevate product aesthetics.
· Core Specifications
| Parameter | Specification |
|---|---|
| Material | 6061-T6 Aluminum (standard); optional: 7075-T6 (higher strength), 5052-H32 (better formability), or brass (for EMI shielding) |

| Standard Sizes | • ID: Ø4 mm to Ø20 mm (in 0.5 mm steps) • OD: ID + 4 mm to ID + 12 mm (e.g., Ø8×12 mm) • Length: 5 mm to 30 mm (custom up to 50 mm) |
| Tolerances | • ID/OD: ±0.01 mm • Length: ±0.02 mm • Concentricity (ID to OD): ≤ 0.01 mm TIR • Squareness (ends): ≤ 0.01 mm |
| Anodizing Thickness | 15 μm (Type II, standard); optional: 25 μm (Type III hard coat) for extreme wear resistance |
| Weight (Example) | Ø8×12×10 mm: ~3.8 g (6061-T6) |
| Max Load Capacity | Axial: 1,500 N (static, 6061-T6, L=10 mm) — verified via compression test |
| Operating Temp. | -40°C to +150°C (anodized Al); up to +250°C (bare Al, no anodize) |
| Compliance | RoHS, REACH, ISO 9001; FDA-compliant (USP Class VI for food-contact variants) |
